ABOUT LEACH
Behind the technology, there is human time.
Not just any company — I want one you'd want to introduce to a friend.
Our concept is simple: AI does the tedious work, and people just press approve. The time that frees up goes back to creating new things — and the more time the world spends there, the more likely world-changing innovation becomes. That's what I run this company to grow.
SUPPORTERS
Leach's appeal is that it places "people" — rather than technology — at the center.

QUESTIONS
FAQ
What kinds of work can AI handle?
Repeating work that goes through papers and tools — orders, invoices, matching delivery slips with orders, typing, totals, internal requests. First we map your work, then split what AI does and what people still check.
What will I learn from the free chat?
Which work is easy to give to AI, which won't pay off, and whether to start with Advice or with the AI System. If helpful, we share a rough price and what to prepare next.
Can I keep using my current tools?
Yes. We design around what you already use — freee, spreadsheets, PDFs, email. We don't change everything. We start where work gets stuck.
How do I choose between Advice and the AI System?
If you want regular help on AI direction and vendor prices, pick AI Advice. If you want a specific work done by a system, pick the AI System. In the first 30-min chat, we'll help you decide.
